LOUIS GROSHOLZ, OF PHILADELPHIA, PENNSYLVANIA.

DRINKING-CUP.

Specification of Letters Patent No. 21,955, dated November 2, 1858.

'lo all whom 'it may concern:

Be it known that I, Louis GRosHoLZ, of the city and county of Philadelphia and State of Pennsylvania, have invented a new and Improved Oollapsing Drinking-Cup; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being' had to the accompanying drawing and to the letters of reference marked thereon.

My invention consists in combining a small cup with one or more rings, both cup and rings having sides inclined at precisely the same angle, and the whole being so arranged, that, when extended, they shall form a water-tight, drinking cup of ordinary capacity, and, when depressed, shall occupy together no more space than the uppermost ring, as more fully described hereafter, the whole forming a portable cup, which can be carried in the pockets of Sportsmen, travelers and others, without any inconvenience to the wearer.

In order to enable others to make and use my invention, I will now proceed to describe its construction.

On reference to the accompanying draw ing, which forms a part of this specification; Figure l, is a sectional view of my improved, collapsing, drinking cup, with the sections fitted together and ready for use. Fig. 2, a sectional view of the relative position assumed by the sections, when the cup is not required for use.

The cup, as illustrated in the drawing, consists of three sections A, B and O, made of silver, britannia ware, or other metal, alloy or other suitable material, the inside and outside of the sections being perfectly true and smooth.

The upper section A consists of a plain, circular ring, larger above than below, with a bead on the upper edge, which serves the double purpose of imparting strength to the section, and aifording a smooth edge for the lips of the drinker. The intermediate section B also consists of a ring, larger above than below, and the lowest section O consists of a cup, with sides inclined at precisely the same angle as those of the upper and in termediate sections.

The diameters of the three sections are such, that the lower end of the upper section overlaps and tits snugly to the upper end of the intermediate section, and the lower end of the latter overlaps and fits snugly to the upper end of the lowest section.

By holding the lower section in one hand and raising t-he others with a slight force, a perfectly tight joint, owing to the accuracy of the fit, will be formed at the points where the sections overlap each other, and the combined sections will thus form a cup, similar to those used for drinking purposes, and one capa-ble of standing erect, without fear of the sections collapsing.

When the cup has been emptied and is not required for further use, a slight pressure is imparted to the upper section, when the upper sections will fall, and the whole will assume the position illustrated in Fig. 2, in which state they may be inclosed within the small box D, and the whole carried in a coat pocket, without any inconvenience to the wearer.

The utility of the above described invention, as a portable drinking cup for travelers, Sportsmen and others, will be apparent without further description.

I do not desire to confine myself to the employment of three sections, inasmuch as two might be used for a small sized cup, and, for those of a larger size, four or five sections might be advantageously employed. But

I claim anddesire to secure by Letters Patent,

As a new and improved article of manufacture, a drinking cup formed of two or more sections with inclined sides, said sections being adapted to and detachable from each other substantially as herein set forth and for the purpose specified.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.

LOUIS GROSHOLZ.
